There's a world of Instagram comments that probably don't make sense unless you're a teenager. If you've been wondering what some of them mean, follow this breakdown.

• Likeback or LB: Writing this is asking someone to like one of your photos back, so that you look a little more popular.
• First/Instant: This is usually used on celebrities' Instagrams, like Kylie Jenner [1]'s, to claim your territory that you were one of the first to see a photo.
• Row for row: Posting this means asking someone to like a row of your photos on Instagram and you'll like one of their rows back.
• Double tap that: This is a fun way of expressing just how much you love a certain photo.
• Insta dump: Using this is to call someone out when they post tons of photos instead of choosing one or spacing it out.
• #l4l/#f4f: These two hashtags break down into "like for like" and "follow for follow." Essentially, you're asking someone to like or follow you, and you'll do the same for them.
• #Instagood/#Instalove: Using either [2] of these two hashtags [3] expresses just how amazing you think a photo is, whether it's a landscape or a person.
